This paper provides a mathematical foundation for independent random matching of a large population, as widely used in the economics literature. We consider both static and dynamic systems with random mutation, partial matching arising from search, and type changes induced by matching. Under...

This research argues that deep-rooted factors, determined tens of thousands of years ago, had a significant effect on the course of economic development from the dawn of human civilization to the contemporary era. It advances and empirically establishes the hypothesis that, in the course of the...

GDP growth is often measured poorly for countries and rarely measured at all for cities or subnational regions. We propose a readily available proxy: satellite data on lights at night. We develop a statistical framework that uses lights growth to augment existing income growth measures, under...

Populism may seem like it has come out of nowhere, but it has been on the rise for a while. I argue that economic history and economic theory both provide ample grounds for anticipating that advanced stages of economic globalization would produce a political backlash. While the backlash may have...

Using data from the 2010-2014 American Community Survey, we use a procedure suggested by Capps et al. (2015) to identify refugees from the larger group of immigrants to examine the outcomes of refugees relocated to the U.S. Among young adults, we show that refugees that enter the U.S. before age...

An influential strand of research has tested for the effects of immigration on natives' wages and employment using exogenous refugee supply shocks as natural experiments. Several studies have reached conflicting conclusions about the effects of noted refugee waves such as the Mariel Boatlift in...

Medical and public health innovations in the 1940s quickly resulted in significant health improvements around the world. Countries with initially higher mortality from infectious diseases experienced greater increases in life expectancy, population, and - over the following 40 years - social...

The economics of climate change involves a vast array of uncertainties, complicating both the analysis and development of climate policy. This study presents the results of the first comprehensive study of uncertainty in climate change using multiple integrated assessment models. The study looks...

In this chapter we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that their...

We study the effects of immigration on native welfare in a general equilibrium model featuring two skill types, search frictions, wage bargaining, and a redistributive welfare state. Our quantitative analysis suggests that, in all 20 countries studied, immigration attenuates the effects of...
